Establishes repeatable operating rules for AI agents, reducing inconsistency and improving reliability in multi-agent or long-running deployments.

A portable SKILL.md operating contract for coding agents — Claude Code, Codex, Cursor, Windsurf, Gemini CLI, GitHub Copilot, and others. It makes the agent bind the task and deliverable up front, act from evidence, convert requirements into concrete checks over the final artifact, edit the smallest possible write set, and verify the result through the same interface a real user will use. Installs per-harness bridge files (for Claude Code: .claude/skills/vowline/SKILL.md plus CLAUDE.md).

Things to check

  • Scanned, not hands-on tested — this entry was auto-scanned from public metadata (GitHub metrics, license, security flags). No reviewer has run it, and no tool-specific limitations have been documented yet.
  • Single maintainer. Consider the risk if this person stops maintaining the project.
